22. Remote Control Signal Receiver
22. Remote Control Signal Receiver
Note
The 80-pin package does not have the PMC1 pin. Use the PMC0 pin for external pulse input.
22.1 Introduction
Remote control signal receiver has two circuits for checking width and period of external pulse.
Table 22.1 lists Remote Control Receiver Specifications, Figure 22.1 to Figure 22.3 show remote control
signal receiver block diagram, and Table 22.2 lists Input/Output Pin.
